Each character will have a set of side quests that you are going to complete for them if you want 100% completion of Code Vein.
In Code Vein, both humans and revenants roam the world. Most of the NPCs in the game only appear in various locations whenever you’ve activated all the Mistles of a location and have completed its main quest or defeated the boss. Make it a habit that whenever you do complete a location to revisit that explored area for these quest givers to appear and to encounter someone new. It is also recommended that you try to complete all the locations before reaching the final location Gaol of the Stagnant Blood so that all the NPCs will appear in the various locations and it’ll be easier for you to find them whenever you take their requests.

Self-Important Revenant Side Quest Guide
Self-Important Revenant is an NPC and Quest Giver in Code Vein. He is a revenant found at the Ruined City Center. Although he may seem tough on the outside, this revenant only wishes to find a shelter for the rest of the surviving revenants. NPCs are individual characters that are encountered during the course of the game that may or may not provide benefits.
First Request: Clear the Park
Location: Parking Garage – Ruined City Center
For this revenant to show up, you’ll have to complete and defeat the boss of the Ruined City Center. Once you’ve completed the requirements, teleport to the Parking Garage Mistle of the Ruined City Center and you’ll find the Self-Important Revenant there. Speak to him and he’ll ask for your help to clear the path of Lost that’s preventing him from exploring further, simply teleport or travel to the Park Ruins Mistle of the Ruined City Center and kill the enemy that’s indicated on your map. Report back to the revenant after killing the enemy and you’ll be rewarded with 1x Loss Shard (M).
Second Request: Cliffs of Rust
Location: Decayed Ship Interior – Dried-up Trenches
For the second quest, make sure you’ve also cleared out and defeated the boss of the said location as well as completed the first request of the Self-Important Revenant. Simply travel to the Decayed Ship Interior Mistle of the Dried-up Trenches and you’ll find the revenant standing next to the ladder, speak to him and he’ll give you 1x Map: Cliffs of Rust and asks for your help to investigate the area for a bloodsping.
Now, Head back to Home Base and speak to Davis to access the Depths: Cliffs of Rust, the location will be marked with a red indicator on your map once you arrive at the depths. All you have to do is follow it, kill the enemies, and clear/complete the depths. After that’s done, report back to the Self-Important Revenant and he’ll give you 1x Condensed Loss Shard (M) as a reward.
NOTE; will not show up until you first complete Ridge of Frozen Souls later in the story.
Third Request: A Shelter for Revenants
Location: Poisonous Butterfly Nest – Ruined City Underground
After completing the second request, the revenant will move to the Poisonous Butterfly Nest where you fought the Butterfly of Delirium at the Ruined City Underground, speak to him and he’ll ask you to find an activated mistle. To find this, teleport to the Research Facility Area Mistle at the Memories of Player then head back to the camp where the rest of the NPCs are such as Karen, Gregorio, Aurora, and other revenants. You won’t miss the item since it will be marked with a white indicator on your map, and you’ll find 1x Mistle Agent on top of the military supplies. Once you have the item, teleport back to the Poisonous Butterfly Nest and hand in the item to the revenant – he’ll reward you with 1x Condensed Loss Shard (L) and 1x RV Mastery (113) for completing his request. Be sure to reset the area and speak to him a final time to trigger a flag for another NPC quest.
